Abstract: Based on the linkage relation of measured segment and gravit y center,the study obtained one circle of gravity center by measuring three loc ations of general gravity center.The error of measuring the location of general gravity center would result in the serious distortion of the general gravity ce nter circle.It was settled by increasing the extent of moving segments and addi ng extra weight to increase central angle and the radius of the circle.Applying the software of analyzing distortion of circle of general gravity center,we mi ght select the experimental project by adjusting the radius and central angle to control the distortion.
Key words:human body; general gravity center circle; distortion |
